The Belimo BFL Series Fire & Smoke Damper Actuators are engineered to provide dependable operation of fire and smoke dampers in HVAC systems, ensuring reliable protection of occupants and property during emergency situations. Manufactured by Belimo Switzerland, a global leader in HVAC actuator technology, the BFL Series is widely installed in commercial buildings, hospitals, schools, hotels, airports, and other facilities where life safety is a priority.
As an integral part of HVAC ventilation systems, the actuator controls the opening and closing of fire and smoke dampers during normal building operation while automatically returning the damper to its fail-safe position in the event of power loss. This helps limit the spread of smoke and fire through ventilation ductwork, supporting safe evacuation and compliance with fire protection requirements.
The BFL Series includes a complete range of models to suit different control and power supply requirements. The BFL24, BFL24-ST, BFL24-T, and BFL24-T-ST models operate on 24 V AC/DC with On/Off control, while the BFL230 and BFL230-T models are designed for 230 V AC applications. For applications requiring proportional airflow control, the BFL24-SR and BFL24-SR-T models provide modulating control for seamless integration with modern building management systems (BMS).
Delivering 4 Nm / 3 Nm output torque, the BFL Series is suitable for small fire and smoke dampers commonly found in commercial HVAC systems. The actuators feature a continuous hollow shaft compatible with 12 × 12 mm square shafts, allowing quick and secure installation without additional mounting accessories.
The actuators typically operate in approximately 60 seconds, while the integrated mechanical spring return mechanism restores the damper to its fail-safe position in approximately 20 seconds during a power interruption. This rapid response helps ensure reliable smoke containment and fire protection performance.
Manufactured in Switzerland, Belimo actuators are renowned worldwide for their precision engineering, long service life, and dependable operation. PGTECH is the official distributor of genuine Belimo products in Vietnam, providing comprehensive HVAC control solutions, technical consulting, and professional after-sales support.
